A bad night for the New York Mets got even worse with the news that star pitcher Jacob deGrom suffered a hyperextended pitching elbow during their 7-0 loss to the Atlanta Braves.

The 29-year-old right-hander had been cruising along, posting four scoreless innings before exiting the game. Nothing appeared to be wrong when deGrom set down the heart of Atlanta’s order in his final frame. However, he immediately departed for the clubhouse once the inning ended and was never seen again.

The injury is almost certain to cost deGrom time. Even if it’s not deemed to be serious, the Mets won’t be sending him out there for his next scheduled start. DeGrom is one of the most important players on the team, as evidenced by his current scoreless streak that reached 18 1/3 innings on Wednesday night, and will be needed at 100 percent.

DeGrom struck out four, while lowering his season ERA to 1.87 in his abbreviated outing.
